Write is yet another Dropbox-friendly text editor for the iPhone, but even in its present state as a teaser video and landing site, it looks amazing. In fact, it looks like it could become my favorite iPhone editor.

Not convinced? Read on…

The app contains a whole bunch of clever functions, and they seems to be packed in without making anything feel cluttered.

First up are the pull-to-save and pull-to-delete gestures. If you have ever used pull-to-refresh, you’ll be familiar with this gesture (although using he same gesture for both saving and deleting files seems like it might be a little dangerous).

Then there’s the cool Quick-Look-style popovers: Long-press a document in the file list and up pops a full, scrollable preview in a popover window. So smart, and so obvious, it should be in every document-based app.

Third is the clever editing mode. Banging out test on an iOS keyboard is easy and fast, but editing and correcting that same text is excruciating. Write app switches the keyboard area to a trackpad when you toggle a little nubbin in the center of the keyboard’s extra row, allowing you to control a cursor, or to move the selection point. Without trying it out, we won’t know how well it works, but it can;t be worse than Apple’s built-in method.

And that’s just the first minute of the video. You Also get Markdown preview, image support and – get this – a (free) companion Mac app which sits in the menubar and syncs with the iPhone app.

Just about the only criticism I have right now is that this is an iPhone app, when it would be perfect on the iPad. And yes, I know that that’s a pretty weak criticism.

There’s no launch date yet, but you can be sure that I’ll be testing it out as soon as it is available.
